WaveLab Pro 9: Tile Audio Windows?

For my usual workflow, I like to see all my open audio files tiled in the workspace. Since upgrading to WL9 (From WL7), I cannot figure out how to do this, nor did a search give me any results.

Does WL9 allow the windows to be tiled?

Thanks

You can split a file group at will. But this is different than the standard tiling.
